Its head is its weak point. Time your attack well -- if you attack when its head is inside its shell a Mega Volt will shoot back at you! TekMissiles are recommended.

Final Fantasy VI Playstation One Bestiary entry

The Ymir, also known as Whelk or "monster who eats thunder", is the first boss of Final Fantasy VI. It is faced at the end of the Narshe Mines during the raid on Narshe. When the imperial forces are in front of the frozen esper's room, one of the Narshe guards sends Ymir to attack the opposing forces, as a last stand against the invasion. It is one of the strongest creatures tamed by the Narshe guards.

Stats[edit | edit source]

Head

Shell

Battle[edit | edit source]

Only one of the two parts needs to be defeated. The head is the easier part to kill, but every ten seconds it hides in the shell and becomes immune to damage until it reappears. The head attacks with a physical attack and Slime, which inflicts Slow on a character. Attacking the shell prompts it to counter with Megavolt, which will take a large chunk of HP from the party. While it is possible to destroy the shell, it will take a long time to destroy it due to its massive HP. Ymir can use Megavolt six times before it runs out of MP.

Strategy[edit | edit source]

It is best to not attack the shell and focus on the head. While the head is out, Biggs and Wedge should use any elemental Magitek beams and Terra should use Magitek Missile. While the head is hiding, the party should use Healing Force and wait until the head reveals itself.

A strategy for a fast victory is to keep using Terra's Magitek Missile without letting the soldiers attack. With luck, the creature will die before it can retract its head.

Strategy

Players likely will have figured out the pattern from the previous two SNES-era bosses: attack, wait, attack, wait, repeat. This boss, however, hits about twice as hard, a fact made worse by its tendency to Slow its target. Ymir doesn't have any particular weaknesses. The player should again time the party's attacks while avoiding a direct hit on the shell and the resulting Megavolt retaliation, curing when needed. The pattern isn't hard to follow, but the fight could be a long one. Keep the pressure up and the rhythm steady for the win.

Etymology[edit | edit source]

In Norse mythology, Ymir is the father of the race of giants and the grandfather of Odin, King of the Gods.

It has also been known as Whelk, and Biggs and Wedge call it "lightning whelk". The lightning whelk is an edible species of large predatory sea snail or whelk, a marine gastropod mollusc in the family Buccinidae, the busycon whelks.
